RICHARD BEGER, OF DEBEN, GERMANY.

TYPE-WRITING MACHINE.

To @ZZ whom. it may concern.: Be it known that I, RICHARD Buena, asubject of the King of Saxony, residing at Deuben, near Dresden,Germany, have invented certain new and useful Improvements in orRelating to Type Writing Machines, (for which I have madeapplication forLetters Patentin France, led December 24, 1898, andY inAnstria, iiledDecember 31, 1898,) of which the following is a specification.

The present invention relates to type-writing machines which can be usedfor code or secret writing.

The invention consists in the arrangement horizontally of two concentricrings, one within the other, each being provided'on its surface withletters and signs, which rings can be relatively displaced one withregard to the other according to a prearranged code or system. Thuswords and letters typed accord.

ing to the outer ring appear on paper printed according to the innerring, the consequence being that the printed Words will have no seemingconnection with one another until rearranged in the manner hereinafterto be described. The receiver then arranges the index-rings of his ownmachine relatively to each other in conformity with the code or systemdecided on-z'. e., in the same manner as the sender had done-copying thetext received according to the letters and signs of the inner ring. Itwill be found that by this method Ithe key of the machine will indicatethe proper signs and letters of the outer ring, thus reproducing thetext received in a manner so as to represent the original text andoriginal connected phrases.

It, for instance, the word Arno had been decided on as the key, theinner ring is set in such a manner that its letter A corresponds or isin line with the small o of the outer ring. Inasmuch as the word Arnocontains four letters, the fact of it containing four letters may beused as an indication that the key has to bev changed every four lines,so as to render the deciphering moreY By relatively displacdifficult tostrangers. ing the rings gradually-for instance, r under 0, then again nunder .o, then ICO iAJ) ICD-7, CA 1,35 under A, and finally r under n,and

n under r-it is possible to change the key in a letter containingfortylines not less than eight times, a fact which renders it almostimpossible for any stranger to decipher the real meaning even afterlong-continued trials.

The arran gementcharacterizing the present invention, and which can beemployed in machines of various constructions, is represented in Figurel bya front view, in Fig. 2 by aseotional View, and in Fig. 3 by abroken plan -vi ew.

The two horizontal concentric rings a and b are connected, respectively,to disks o. b', the ring b being arranged so as to be rotatable on thelarger disk a', on which, however, it

can be secured by means of a clamping-screw c. The outer edge ot theinner ring b is overlapped by the edge of the outer ring or, fastened toor forming part of ther disk a'. The latter is rigidly-connectedwith theframe d of the type-writing machine, while the shaft e, carrying thekey'f, passes loosely through the two disks a' o. The key f, which ispressed upward by the spring g, engages with its hook h in oneY of theteeth i, arranged on the under side or flange of the disk of, and isthereby steadily held in position. The type-wheel is arranged verticallyand is actuated by the shaft e by means of bevelgearing in such a mannerthat by-turning the key f toa desired position or letter on the outerring a and locking the hook between the corresponding teeth of the diskin this position'the correspondingletter on the typewheel Z will bebrought to its lowest position, when it is impressed on the paper placedunderneath it. This arrangement for the production of code-writing canalso be applied to type-Writing machines of other constructions, myinvention' being characterized by two concentric letter-rings movablerelatively to each other. l

I claiml. The combination with two horizontallyarranged concentricsign-rings, one of which is relatively movable as regards the other, atype -wheel arranged vertically below the rings, an operating-shaftextending centrally through the inner ring and rotatable inde- ICOpendently thereof, and gearing between the to be engaged by the key, andgearing beshaft eind the type-wheel. tween the type-Wheel and the shaft.
